An object is to print a high quality image with resistance to print misalignment. To this end, the image processing apparatus generates quantized data for printing a first dot pattern and a second dot pattern in an overlapping manner. The first dot pattern and the second dot pattern are lattice patterns varying in a combination of two basis vectors. In a combined dot pattern obtained by combining the first and second dot patterns, there is a neighboring dot in which a dot in the first dot pattern and a dot in the second dot pattern are arranged at an interval smaller than a lattice spacing. The neighboring dot includes multiple neighboring dots varying in an approach direction.

Bidirectional multi-pass printing with three or more passes prints a high-quality image with reduced time difference unevenness. To this end, an image in a unit region on a printing medium is printed by a print head performing 2N+1 bidirectional print scans (where N is a natural number). In this printing, a print permission rate for an even-numbered print scan of the 2N+1 times of the print scans is set lower than the print permission rate for an odd-numbered print scan of the 2N+1 times of the print scans.

The first trend chart is generated based on a plurality of first representative value arrays obtained from a plurality of mass spectra. The second trend chart is generated based on a plurality of second representative value arrays obtained from the plurality of mass spectra. A mass spectrum stable period is determined based on the first trend chart and the second trend chart.

A first dot pattern printed according to a result of quantization performed on a multi-valued grayscale value by using a first threshold matrix and a second dot pattern printed according to a result of quantization performed on multi-valued grayscale value by using a second threshold matrix are printed on a print medium in an overlapping manner. In order to generate the threshold matrices, a first initial pattern being a dot pattern corresponding to a first grayscale value and a second initial pattern being a dot pattern corresponding to a second grayscale value lower than the first grayscale value are generated for pixel regions of the first and second threshold matrices. Then, thresholds of the first and second threshold matrices are set such that dot patterns having continuity with the first and second initial patterns are obtained at grayscale values between the first and second grayscale values.

A converting apparatus includes a converter, an extractor, and a generating unit. The converter converts print data described in a first description language into print data described in a second description language. The extractor extracts command information related to an imposition process from the print data described in the first description language. The generating unit analyzes the command information extracted by the extractor so as to generate information for specifying print-layout definition information to be used from multiple pieces of print-layout definition information stored in a printer that is to execute a printing process. The multiple pieces of print-layout definition information have different imposition processes defined therein.
